Why buy from B&B

Because you work directly with a family-run business that cares about getting it right.

B&B Firearms is built on faith, family, service, and real product knowledge. When you buy here, you are not supporting a giant corporation — you are working with a veteran-owned family business that values honesty, guidance, and doing right by people.

A feature rich rifle with a blend of carbon fiber and accuracy. If you’re considering a large frame patterned AR platform in calibers other than the tried and true .308, then look no further. The NEMO Arms XO in 20-inch trim is a lightweight, accurate, hard hitting carbine. Available with a 20-inch Proof Research barrel. The longer barrel ensures that you can extract maximum velocity from your projectiles. Ambidextrous controls make operating the XO a cinch for any shooter.
